Eddy covariance towers and soil respiration system
(Licor 8100) in a Midwest prairie (IL, USA)
Terrestrial natural and agricultural ecosystems critically regulate the concentration of greenhouse gases (CO2, CH4 and N2O) in the atmosphere, the water and energy cycles and they provide food, energy and fiber through biogeochemical cycles. These systems are in turn strongly affected by changes in the environment.
My research focuses on addressing these major unsolved questions:
- How are terrestrial ecosystems affected by changes in land use and climate, and how do ecosystems interact with the global environment?
- How can we improve the environmental and ecological sustainability of agroecosystems and managed systems?
To answer these questions, I use empirical, modeling and synthesis approaches and integrate knowledge across disciplines (plant and soil sciences, ecology, agronomy, environmental science). My research uses a variety of tools including plant, soil and ecosystem methods (stable isotopes, canopy and soil chambers, eddy covariance technique) to measure an array of processes across multiple temporal (past, present and future) and spatial (local, regional, global) scales.
